Yesterday we put the finishing touches on a backsplash. This particular splash was straight forward: 4x4 on diagonal with an irregular edge. The grout is SpectraLOCK Grout which is a stain proof grout that dries to a porosity of .05% making it less porous than the tile itself. This means that oil, spaghetti sauce, etc can not absorb into the grout joint. Jason is watching over his helper Gary, as he touches up a few spots.
